RHZK6.8/B Positive Pressure Air Breathing Apparatus

scenarios. Advantages:
- Excellent Safety Performance: The gas cylinder burst pressure is ≥102MPA, and the hydrostatic test pressure is 50MPA, far exceeding the rated filling pressure of 30MPA. The multi-layer composite structure provides pressure relief protection, avoiding the risk of bursting and splashing.
- Lightweight Design: The gas cylinder weighs only 3.8Kg, significantly lighter than traditional steel cylinders, reducing physical exertion for the wearer and suitable for long-term operation.
- Extra-Long Service Life: 15-year service life, significantly better than ordinary similar products, reducing equipment replacement frequency and improving cost-effectiveness.
- Smooth Breathing: With a breathing resistance of ≤700pa (at 25 breaths/min) under basic working conditions, the breathing resistance is low, providing comfortable wear without a feeling of suffocation.

Product Features:
- High-Quality Cylinder Material:  Adopts a multi-layer composite structure of 6061 aluminum alloy inner liner + carbon fiber first interlayer + glass fiber second interlayer + epoxy resin outer shell, combining strength and corrosion resistance.
- Precise Thread Adaptation: The bottle valve has an internal thread of G5/8 and an external thread of M18X1.5-6H, compatible with standard filling equipment, ensuring a secure connection without leakage risk.
- Environmentally Friendly Gas Medium: Can be used with ordinary air, eliminating the need for special gas preparation, resulting in low and convenient operating costs.
- Standardized Parameters: Complies with relevant fire-fighting equipment standards such as GA124-2013, with an REE parameter of 122, ensuring product universality and compliance.

Applicable Scenarios:
- Fire Fighting Operations: Suitable for various fire scenes, isolating smoke and toxic gases, and ensuring the respiratory safety of firefighters.
- Hazardous Chemical Handling: Can be used in toxic and harmful gas environments, such as chemical plants and hazardous chemical transportation leaks.
- Oxygen-Deficient Environment Operations: Suitable for rescue work in oxygen-deficient environments such as underground spaces, deep wells, and caves.
- Industrial Safety Protection: Used for emergency rescue and daily high-risk operation protection in industries such as petroleum, smelting, and mining.

Usage and Maintenance Points:
- Filling must be done using standard air filling equipment, strictly adhering to the rated pressure of 30MPA to avoid overpressure. - Regularly perform water pressure testing to ensure the safe performance of the gas cylinder. The testing cycle must comply with relevant special equipment management regulations.
- Store in a dry and well-ventilated environment, avoiding direct sunlight and impact from heavy objects, and keep away from corrosive substances.
- Before use, check the sealing of the valve connection and whether the pressure display is normal.  Ensure the equipment is free of defects before wearing it.
